I used this motor (12-3CT)for the nats last week. It has a large power window and easily made time despite not being fully broken in. Comparing it to OS Speed motors at the track, this motor had better rip at the bottom and mid range but lost out a little in the top. I was geared for this and didn't have time to experiment with pipes. On top of the great power and mileage this unit gave me, after a gallon or so of fuel, the motor could still use some running in. I predict this motor will last quite a while. Hope this helps.

Do i need to replace the crank if i convert the LS5 to an LS3? or just the Piston & liner?

FEATURES:
-Natural aluminum construction Nine fin blue aluminum cooling head
-Two-piece turbo cylinder head with 29mm innner and 49mm outer head
that adds extra area for more efficient cooling
-Slide Carb 11H - 3 needle slide valve carburetor with ROAR/IFMAR legal 5.5mm carb restrictor
-Rear Exhaust
-ABC construction, Aluminum piston and Brass liner that is Chrome plated
-High tensile A7075 "knife edge" aluminum connecting rod double bushed for friction-free operation.
Don’t confuse compression with pinch, Sleeve Pinch is not that important contrary to popular belief. The question is how well does it seal as soon as the piston starts to close the exhaust port and if it holds compression after you roll it to top dead center.
Place a few drops of after run oil trough the top (removing plug), then place plug in place, then roll piston to top dead center and listen and look for air bubbles through exhaust port. If there’s none, then your engine still has compression, even if it has no pinch.
The fastest team motors we have, have zero pinch.

My bday is coming up, and my wife finally "allows" me to buy a new engine. I like OS TZ tuned better, because I am used to tune OS engine. Plus 12-3C seems to me is a better deal, cheaper and equal in performance. But, I heard NovaRossi is harder to tune than OS engine. That is why I would to hear some comments regarding these to engines. Thx.

when Novarossi means NON TURBO, it refers to the crankshaft, not the glowplug, the non turbo shaft is EFRA legal and its tunel is smaller than the turbo style, which is not efra legal.......
